Abstract: 395,436. Discharge lamps. PROUTY, W. 0., 719, Pier Avenue, Hermosa Beach, California, U.S.A. Feb. 11, 1932, No. 4124. [Class 39 (i).] A portable ultra-violet lamp, particularly adapted for therapeutical use is housed in a container having one compartment for the terminals of the tube, and another, distinct from the first, contains means for supporting the tube proper, which is spaced from the wall of the housing. In one form, Fig. 2, the tube 11 is coiled back on itself and is supported in a cast aluminium chamber 14 by asbestos rope 35. The chamber 14 has an aperture 15, Fig. 3, which may be closed by a shutter 16 operated by a handle 17. The electrode chambers 12, 13 are supported in slots in an insulating block 25 to which the lead-in conductors are secured by screws 27. The block is carried with a pad of sponge rubber and the chamber 14 is closed by a plate 20 carrying a cushion 21 of sponge rubber. For confined application, a side tube 39 is provided and its aperture may be further reduced by a bayonet lock cap 38 carrying a quartz applicator 37. In a modification, Fig. 6, the housing 46 is made in two halves, one carrying the terminal block 51 and the other a sponge rubber pad in corresponding position. The tube is supported by a sponge rubber block 57 and an applicator 43 is mounted opposite a projection 58 on the tube. The housing 46 is indented to permit of easy handling. In another modification the tube is coiled spirally and is secured by studs and wire ties mounted on a "dish pan" shaped container which may be polished to act as a reflector. The terminal blocks are mounted in an offset portion of the container which may be shaped as a handle. The tube may be filled with a noble monatomic gas such as neon, argon, helium or krypton at a pressure of from 4 to 12 mms. with or without a few drops of mercury. The tube diameter should be less than 7 mm. and preferably 3 or 4 mm. A high potential, above 1000 volts should be applied giving a current of 50 milliamps.

Abstract: 504,585. Ice-making. STONER, R. M. Feb. 10, 1938, No. 4212. Convention date, Feb. 16, 1937. [Class 29] A mould for freezing liquids so as to produce non-rectangular cubes comprises a grid assembly of two or more inclined partitions 8, Figs. 3 and 4, mounted in slots 9, 10 in longitudinal members 7a, 7b. The part 7a of the longitudinal member may be actuated by a lever 12 to slide over the fixed part 7b to cause angular movement of the partitions 8 to release the blocks. The notches 9 decrease in size from one-end of the grid to the other, so that the ice blocks are released one after the other. The lever 12 may be so pivoted as to cause a raising of the grid assembly during its operation. In a modification the member 7a is in the form of a narrow strip having a series of slots through which pass projections on the lower member 7b. Specifications 489,247 and 490,748 are referred to.

The lens may be provided in a sheet of flexible material stretched across a flat open-topped container. When the receptacle contains more than one stylus a corresponding number of lenses may be provided. In another embodiment, Fig. 5, the receptacle comprises a tube 1 having a lens 6 forming a removable closure. The opposite end of the tube may contain a brush 9, for dusting the stylus point, directed away from the lens and provided with a protective cover 10.

Title: Improvements in or relating to Frequency and Phase Comparators
IPC: H02P7/29
Filed: 1968-01-29
Abstract: 1,196,372. Automatic control of speed. WESTEL ASSOCIATES, WESTEL Inc., and WESTEL CALIFORNIA INVESTORS. [trading as WESTEL CO.], Jan.29 1968 [March 24, 1967], No. 4459/68. Heading G3R. The frequency and phase relationship of two pulse trains F and R is determined by respective comparators 28, 32 whose outputs are selectively connected to a "control signal" terminal 110 by switch means 36 responsive to the frequency comparator. The frequency comparator 28 employs logic circuitry to set and reset flip-flops A, B and C, and the arrangement is such that the output A, which is connected to the switch 36 is normally switched to 1 by an R pulse and to 0 by an F pulse but is held in a "1" state when two R pulses occur in the interval between two F pulses until two F pulses occur in the interval between two R pulses, and similarly is held in a "0" state when these events occur in the reverse order. The phase comparator 32 comprises a ramp generator 94 which is triggered by each R pulse and a capacitor 96 which is connected to the ramp generator when a field effect transistor 98 is gated on by the F pulses applied to diode 100. Thus the charge on the capacitor at any time is that voltage which the ramp reached when the last F pulse occured, and so is a measure of the phase displacement. The output S is also connected to the switch 36, and by means of OR gates 104, 106 and the outputs of flip-flop C either A or S is connected to terminal 110. This arrangement is such that, when F and R occur alternately phase signal voltage S is connected but when two F (or R) pulses occur between two R (or F) pulses then A is connected instead, and this will be "0" or "1" according to whether F is faster than R or vice versa. The signal at 110 is used to control a D.C. motor 10 driving a load 14 (a tape capstan) and an F pulse generator 16 comprising an impulse wheel 20.

Abstract: 1492515 Delivery of samples for spectroscopy BODENSEEWERK PERKIN-ELMER & CO GmbH 5 Feb 1976 [20 Feb 1975] 04592/76 Heading G1B [Also in Division G2 ] Samples to be atomized for atomic absorption spectroscopy are drawn sequentially from one of a series of sample containers 16 by a sample pump 38 extracting flushing fluid from the pipe system 10 and thus drawing the sample into movable pipe 12. An air pump 36 first draws an air bubble into the system to isolate the sample. The pipe 12 is moved to the delivery position 18 at which the sample is deposited in the spectroscope. A flushing pump 24 pumps flushing liquid from the container 22 through the apparatus between samples, discharging into 14. Thus cross-contamination of the samples is avoided. The sample containers are carried on a turntable and successively presented to the sampling station.

Abstract: 1287517 Gas blast switches; electrically released switches LICENTIA PATENT-VER WALTUNGS GmbH 30 Jan 1970 [5 April 1969] 4717/70 Heading H1N A circuit breaker has two hollow movably mounted contacts 4, 5 in a compressed gas filled enclosure 3, the first contact 5 being latched in the closed position and urged to the open position by the pressure of the gas while the other contact 4 is resiliently mounted to initially follow the contact 5 in the opening movement. The latch is a resilient ring 27 expanded by a nmber 11 which can be withdrawn by a tripping linkage 23-25 (Fig. 2, not shown), whereupon the gas in chamber 3 drives a piston 9 to the right to open the contacts; valve members 13, 14 are also separated and a blast passes through the hollow contacts. After a delay the pressure in the outlet passages 22 acts on pistons 16 to close off outlets 15. Compressed gas is applied to conduit 18 to reclose the contacts by means of a piston 19; a valve 21 is also opened to allow the exhaust valves 15, 16 to re-open. The tripping rod 23 may be operated, through an expansion compensating hydraulic coupling (Fig. 2, not shown), by a piston permanently subject to compressed air but normally latched; this latch is then withdrawn by an electrodynamic device energized from a charged capacitor by an overload responsive relay.
